STOVE LEG.

Application filed September 17, 1920. Serial No. 410,857.

1 0 all whomit may concern:

Be it known that I, RU OLPH HOFFMAN, a citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Stove Legs, of which the following is a specification.

The invention relates in general to stoves, such as gas or oil cook stoves, and its aim is directed more particularly to an improved manner of constructing the legs of the stove from sheet metal.

Stove legs have in the past been commonly constructed from a single piece of metal of angular formation and shaped at the upperend to provide shoulders upon which may rest the portions of the stove superstructure. This method of construction has been relatively expensive and the proper and accurate shaping of the upper end of the leg to provide the supporting shoulders has been accomplished only'with considerable difficulty. y y

The object of my invention is to overcome the objections to the former construction, and thisobject is attained by constructing the leg from separate pieces of sheet metal in a novel and advantageous manner which. will be apparent as thedescription proceeds. I I

1 A1 further object of the invention is.to provide a stove leg of sheet metal construction andyet of a strong and rugged character.

In the accompanying drawings wherein I have illustrated a preferred form of the invention, Figurel is a fragmentary perspective view of stove having supporting legs constructed in accordance with my invention. Fig. 2 is a fragmentary elevation of the improved legwith ,the portions of the stove superstructure which are secured thereto shown in section. .Fig. 3 is a fragmentary perspective view of the stove leg, showing particularly the stiffening means therefor. Fig. 4 is a perspectlve view of the upper portion of the leg attached. Fig, 5 is aplan view of the completed .leg detached from the stove. Fig. 6 is a plan view of the blank from which the lower or main portionof the leg is formed. Fig. 7 is a cross'sectional' view ofthe lower portion 'of'the1eg'. Fig. '8 is a fragrnem esasen Seaman view through niec treme 'lower end of the leg showing the construction of the foot portion therefor.

In the drawings, 7 designates generally the lower or base portion of the stove leg having secured at its upper end a top portion or shoe 8 in such relation as to provide annular shoulders upon which the depending portions of the stove superstructure may rest as will be more fully explained hereinafter. The lower or main portion 7 of the leg is formed from a single sheet of metal of sufiiciently heavy gauge, cut to provide a blank such, for example, as that shown in Fig. 6. Said blank is bent along a central longitudinal line into angular form to provlde the side portions or walls 9 and 9 of the leg; and the upper end of the blank is shaped to rovide two substantially triangular portions 10 and 10 bent upon transverse lines near the upper end of the blank into substantially right-angular relation with reference to the side portions 9 and 9 When the triangular portions 10 and 10? are thus bent into a substantially horizontal positiomthe adjacent edges thereof abut as shown in Fig. 3 and may be secured together as by welding. The two portions 10 and 10' when thus secured together constitute a rigid top plate for the lower or base portion of the leg.

The upper portion or supporting shoe 8 of the leg (Fig. 4) is formed from a sheet of metal separate from that of the blank from which the lower portion is formed, and comprises a plate 12 of a shape generally similar to that of the top plate 10, 10'' and having at its outer edges upturned flanges 13 and 13 and at its rear or inner edge an upturned flange 14 carrying a hori- Zontally disposed lug 15. Suitable apertures 16 are provided in the to plate 10, 10. and in the plate 12 0f the upper portion 8, through which apertures are entered rivets 18 by whichthe two portions of the leg may be rigidly secured together. The plate 12 when thus secured upon the top plate 10. 10 serves to further secure the portions of the top plate and hence the side portions orwalls 9 and 9 in fixed relationship.

jthe apsrancingflaages is te -enact with 2). 7 That is to say, the shoe 8 is secured in position upon the top plate 10, 10" with the flanges l3 and 13 offset inwardly from the side portions 9' and .9 of the leg base. Upo-n these shoulders 19 rest the depending edge portions of the bottom of the stove super-. structure as shown in Fig. 2. Thus the stove bottom 20 is shown as having'hdepending flange 21 reinforced byan angular strip 22 secured upon the under side 'oi 'the bottom 20 by means 01? rivets 23. A securing band 241 is secured upon the outer side of the depending flange 21 and to the upstanding fianges'13 and 13 of the shoe 8 as 'by means ofrivets 25, the latter extending also through the reinforcing strip 22 and thus rigidly securing the several parts together. The horizontally disposed lug 15 at the rear portion of the supporting shoe .8 is p p plate shoulders upon which sald edge adapted to engage with'the under side of the bottom 20bit the stove, andis rigidly u d he h h t e hy mea ,Qf r e 26. v r

For the purpose of strengthening the lower portion of the leg, I emplo'y'a member 27 secured within and bridging'the angle. This member preferably extends substantially throughout thelength of the lower por- H 1 7 a d f r Sec ring i in posit-1 ,11, h s.

opposite edge flanges 28 which may be spot welded or otherwise secured to the walls or' V the angle "It w l he ha this m b r s v s t tie th s de Porti ns or w l 9 I an .9 toge her thro gho t manager of .ing.

Thus, it consists o f astrip of-metal bent to-form main fold 30 andan inner'fold31 and the lower end of the leg is inserted'within the main f ld and'whe he f ds are comp e sed finally secured together asby soldering-or welding, The obvious advantage in this construction is that. thelower end of the legs will not injure the floor or floor coverwill be apparent that I have provided a. novel and advantageousconstruction. for stove legs enabling their manufacture kata relatively low cost and at the same time pro viding a construction of a very practical character adapted to support the stovesuperstructurein a thoroughly efficient and practical manner. It is, of course, to..be

understood that the invention is not-limited to details of construction hereinshown and descrlbed in'connection with the embodimen f th nventi n selee ed fer purpese of illustration, and especially is not limited to the particular arrangement of the parts of the stove oi the superstructure to which theleg is secured. Obviously however, the shoulders 19 upon which the portions of the superstructure rest may be made of any desired width by properly positioning the supporting shoe 8 with reference to the top .plate 10, 10 of the lower orbase portion 7.

This application is a continuation in part of my copending application, Serial No. 395,487, filed July 12, 1920.
